Shading composition

ABSTRACT

The present invention relates to a composition comprising at one photocatalyst and at least one azo dyestuff and/or at least one triphenylmethane dyestuff, which produces in the CIElab color coordinate system a relative hue angle of 220-320°, to a detergent composition, a fabric softener composition as well as to a shading.

The present invention relates to a composition comprising at least one photocatalyst and at least one azo dyestuff and/or at least one triphenylmethane dyestuff, which produces in the CIElab colour coordinate system a relative hue angle of 220-320°, to a detergent composition, to a fabric softener composition as well as to a shading process using such a mixture.

A frequently employed method in bleaching and whitening is to use violet or blue dyes concurrently in order to improve the bleaching and whitening effect. If such a dye is used in conjunction with a fluorescent whitening agent, this can serve two different purposes. On the one hand, it is possible to try to achieve an increase in the degree of whiteness by compensating for the yellow of the fabric, in which case the white shade produced by the fluorescent whitening agent on the fabric is largely retained. On the other hand, the object can be to effect with the dye in question a change in the shade of the white effect produced by the fluorescent whitening agent on the fabric, in which case too an attempt is made additionally to achieve an increase in the degree of whiteness. It is thus possible to adjust the desired shade of the white effect.

Shading processes of materials such as paper and textile fabrics are known from e.g. DE 3125495.

These disclosed shading processes, respectively the disclosed mixtures of photocatalyst and dyestuff are not suitable for a regular use, such as in detergent or softener formulations, because the dyestuffs do accumulate with every use and after a few uses the fabrics are coloured.

Therefore, the goal of the present invention was to find a mixture of at least one photocatalyst and at least one azo and/or triphenylmethane dyestuff, which does not lead to a colouration of the fabric.

This problem was solved by a composition comprising at least one photocatalyst and at least one azo dyestuff and/or at least one triphenylmethane dyestuff, which produces a relative hue angle of 220-320°, which is not light stable. That means that the components of the mixture, when applied to the fabric are destroyed by light.

Surprisingly, when the dyestuff as such (without the photocatalyst) is applied to the fabric, it is not destroyed (or destroyed much slower).

Therefore the present invention relates to a composition comprising at least one photocatalyst and at least one azo dyestuff and/or at least one triphenylmethane dyestuff, which produce a relative hue angle of 220-320° and wherein the dyestuff component is degraded when the composition is exposed to light.

Colour coordinates and colour differences are expressed using the internationally standardized CIELAB tristimulus values:

-   a*=red−green (+,−) -   b*=yellow−blue (+,−) -   L*=lightness (light=100) -   C*=chroma -   H*=hue (angle of 0°=red, 90°=yellow, 180°=green, 270°=blue),     and the colour differences ΔE*, ΔH*, ΔC*, ΔL*, Δa*, and Δb*,     together with an identification number of the sample.

This internationally accepted system has been developed by CIE (“Commission Internationale de I'Éclairage”). It is for example part of DIN 6174: 1979-01 as well as DIN 5033-3:1992-07.

Preferably the present invention relates to a composition comprising at least one photocatalyst and at least one azo dyestuff and/or at least one triphenylmethane dyestuff, which produce a relative hue angle of 220-320° and wherein the dyestuff component is degraded when the composition is exposed to sunlight.

More preferably the present invention relates to a composition comprising at least one photocatalyst and at least one azo dyestuff and/or at least one triphenylmethane dyestuff, which produce a relative hue angle of 220-320° and wherein the decrease rate of the azo dyestuff(s) and/or the triphenylmethane dyestuff(s) is at least 1% per 2 hours, preferably at least 2% when the composition is exposed to sunlight.

The degradation of the components can be determined spectrophotometrically.

are:

Preference is given to the group

Suitable heterocyclic rings in the group

are likewise the groups listed above, the bond to the other substituents merely being via a carbon atom.

All of the aforementioned nitrogen heterocycles can also be substituted by alkyl groups, either on a carbon atom or on another nitrogen atom in the ring. The alkyl group is preferably the methyl group.

A⁻ _(s) in formula (1a) is, as a counterion to the positive charge on the remainder of the molecule, any anion. In general, it is introduced by the preparation process (quaternization).

The anion can however also be any other anion since the anions can be readily exchanged in a known manner; A_(s) ⁻ can thus also be a sulfate, sulfite, carbonate, phosphate, nitrate, acetate, oxalate, citrate, lactate ion or another anion of an organic carboxylic acid. The index s is the same as r for monovalent anions. For polyvalent anions, s has a value ≦r, in which case it must be chosen, depending on the conditions, such that it exactly balances the positive charge on the remainder of the molecule.

The granulates E) are prepared according to known methods. Any known method is suitable to produce granules comprising the inventive mixture. Continuous or discontinuous methods are suitable, Continuous methods, such as spray drying or fluidised bed granulation processes are preferred.

Especially suitable are spray-drying processes in which the active ingredient solution is sprayed into a chamber with circulating hot air. The atomisation of the solution is carried out using single or binary nozzles or is brought about by the spinning effect of a rapidly rotating disc. In order to increase the particle size, the spray-drying process may be combined with additional agglomeration of the liquid particles with solid nuclei in a fluidised bed that forms an integral part of the chamber (so-called fluidised spray). The fine particles (<100 μm) obtained by a conventional spray-drying process may, if necessary after being separated from the exhaust gas flow, be fed as nuclei, without being further treated, directly into the spray cone of the atomiser of the spray-dryer, for the purpose of agglomeration with the liquid droplets of the active ingredient. During the granulation step, the water can be rapidly removed from the solutions comprising phthalocyanine compound, and, where appropriate, further additives, and it is expressly intended that agglomeration of the droplets forming in the spray cone, i.e. the agglomeration of droplets with solid particles, will take place. Preference is given to the use of agglomeration processes to produce the granulates according to the invention because such processes usually yield a higher bulk weight so that the granulates have better compatibility with washing agent formulations.

A further embodiment of the present invention comprises using, for preparation of the granulates, phthalocyanine solutions that have been purified by membrane separation procedures.

If necessary, the granules formed in the spray-dryer are removed in a continuous process, for example by a sieving operation. The fines and the oversize particles are either recycled directly to the process (without being redissolved) or are dissolved in the liquid active ingredient formulation and subsequently granulated again.

The granulates are resistant to abrasion, low in dust, free-flowing and can be readily metered. They are distinguished especially by very rapid solubility in water.

The granulates E) preferably have a density in the range from 500 to 900 g/l, dissolve rapidly in water and do not float on the surface of the washing agent solution. They may be added in the desired concentration of the phthalocyanine compound directly to the washing agent formulation.

The content of granulates E) in accordance with the invention in the formulations according to the invention is from to 0.001 to 1 wt-%, preferably from 0.001 to 0.05 wt-% and very especially from 0.005 to 0.03 wt-%.

The washing agent formulation according to the invention can be prepared in a generally known manner.

A formulation in powder form can be prepared, for example, by first preparing an initial powder by spray-drying an aqueous slurry comprising all of the afore-mentioned components except for components D) and E) and then adding the dry components D) and E) and mixing all of them together. It is also possible to start from an aqueous slurry which, although comprising components A) and C), does not comprise component B) or comprises only a portion of component B). The slurry is spray-dried; component E) is then mixed with component B) and added; and then component D) is mixed in dry. The components are preferably mixed with one another in such amounts that a solid compact washing agent composition in granule form is obtained, having a specific weight of at least 500 g/l.

In another preferred embodiment, the production of the washing agent composition is carried out in three steps. In the first step a mixture of anionic surfactant (and, where appropriate, a small amount of non-ionic surfactant) and builder substance is prepared. In the second step that mixture is sprayed with the major portion of the non-ionic surfactant and then, in the third step, peroxide and, where appropriate, catalyst, and the granulate according to the invention are added. That method is usually carried out in a fluidised bed. In a further preferred embodiment, the individual steps are not carried out completely separately, so that there is a certain amount of overlap between them. Such a method is usually carried out in an extruder, in order to obtain granulates in the form of “megapearls”.

As an alternative thereto, the granulates according to the invention can, for the purpose of admixture with a washing agent in a post-dosing step, be mixed with other washing agent components such as phosphates, zeolites, brighteners or enzymes.

A mixture of that kind for post-dosing of the granulates is distinguished by a homogeneous distribution of the granulates according to the invention in the mixture and can consist of, for example, from 5 to 50% granulates and from 95 to 50% sodium tripolyphosphate. Where the dark appearance of the granulate in the washing agent composition is to be suppressed, this can be achieved, for example, by embedding the granules in droplets of a whitish meltable substance (“water-soluble wax”) or, preferably, by encapsulating the granules in a melt consisting of, for example, a water-soluble wax, as described in EP-B-0 323 407 B1, a white solid (e.g. titanium dioxide) being added to the melt in order to reinforce the masking effect of the capsule.

The detergent may also be formulated as an aqueous liquid comprising 5-50, preferably 10-35 wt-% of water or as a non-aqueous liquid detergent, containing not more than 5, preferably 0-1 wt-% of water. Non-aqueous liquid detergent compositions can contain other solvents as carriers. Low molecular weight primary or secondary alcohols exemplified by methanol, ethanol, propanol, and isopropanol are suitable. Monohydric alcohols are preferred for solubilizing surfactant, but polyols such as those containing from 2 to about 6 carbon atoms and from 2 to about 6 hydroxy groups (e.g., 1,3-propanediol, ethylene glycol, glycerine, and 1,2-propanediol) can also be used. The compositions may contain from 5 wt-% to 90 wt-%, typically 10 wt-% to 50 wt-% of such carriers. The detergents can also be present as the so-called “unit liquid dose” form.

The fabric softener compositions preferably have a pH value from 2.0 to 9.0, especially 2.0 to 5.0.

The fabric softener compositions can, for example, be prepared as follows:

Firstly, an aqueous formulation of the cationic polymer is prepared as described above. The fabric softener composition according to the invention is usually, but not exclusively, prepared by firstly stirring the active substance, i.e. the hydrocarbon based fabric softening component, in the molten state into water, then, where required, adding further desired additives and, finally, adding the formulation of the cationic polymer. The fabric softener composition can, for example, also be prepared by mixing a preformulated fabric softener with the cationic polymer.

These fabric softener compositions are traditionally prepared as dispersions containing for example up to 30 wt-% of active material in water. They usually have a turbid appearance. However, alternative formulations usually containing actives at levels of 5 to 40 wt-% along with solvents can be prepared as microemulsions, which have a clear appearance (as to the solvents and the formulations see for example U.S. Pat. No. 5,543,067 und WO-A-98/17757).

Examples of suitable textile fibre materials which can be treated with the liquid rinse conditioner composition are materials made of silk, wool, polyamide, acrylics or polyurethanes, and, in particular, cellulosic fibre materials and blends of all types. Such fibre materials are, for example, natural cellulose fibres, such as cotton, linen, jute and hemp, and regenerated cellulose. Preference is given to textile fibre materials made of cotton. The fabric softener compositions are also suitable for hydroxyl-containing fibres which are present in mixed fabrics, for example mixtures of cotton with polyester fibres or polyamide fibres. The following Examples serve to illustrate the invention without the invention being limited thereto. Parts and percentages are by weight unless specified otherwise. Temperature is given in degree Celsius unless specified otherwise.

EXAMPLES

Degradation Experiments

The aqueous mixture of the photocatalyst and the dyestuff or the components alone were exposed in the given concenctration in a closed 250 ml glass bottle, containing 125 ml of the mixture to sunlight. The intensity measured with a Roline RO-1322 Digital Lux meter in front of the bottles was within the range of 4500-6000 Lux.

The degradation of the components was determined from spectrophotometric data gained HP 8452 Diode array spectrophotometer. The absorption of the mixtures was measured at the respective absorption maximum of the components.

(Photocatalyst 670 nm, Dyestuff 550 nm). While there is only a small overlap of the two absorption spectrum at the maximum absorption of the photocatalyst at 670 nm, there may be an appreciable overlap at the absorption maximum of the dyestuff. The absorption was determined at the start and then every 2 hours. The loss after two hours is given in percentage of the initial concentration and is corrected where the overlap is considerable.

The used photocatalysts are

-   Photocatalyst 1: mixture of sulfonated Al- and Zn     tetrabenzo-tetraaza-Porphyrines (Tinoluxe® BMC liq) -   Photocatalyst 2: sulfonated Zn tetrabenzo-tetraaza-Porphyrine

The used dyestuffs are those of formula (A) and (B) as defined on epage 13.
